Info about U.V.S. Nirmana:

Official game description:
**U.V.S. Nirmana** is an engineering puzzle game from Coincidence, the creators of Kaizen: A Factory Story and the inventors of the Zach-like.
Set off on the Unreturning Void Ship Nirmana as it continues a journey of uncountable eons toward the edge of the universe. Stop by distant worlds and ancient civilizations, helping them as part of your pilgrimage with your companions, the Renunciants.
The U.V.S. Nirmana awaits.
**Thirty Zach-like Puzzles to Master**
--------------------------------------
Conduits, signals, and constraints must be brought into accordance with optimal patterns. Design pipe networks that route energy flows from the vega drive engine and other sources. Modify their behavior with the control matrix while minimizing flux.
**A Medium-Difficulty Pilgrimage**
----------------------------------
Too easy is too easy. Too difficult is not rewarding. For those already experienced with previous “Zach-like” games, a complete journey will take roughly 4–6 hours.
**Twelve Tools for Expedient Means**
------------------------------------
Tools include sensors, valves, multiplexers and more. Their skillful use will be necessary to assist the various life forms and civilizations that you will encounter along the way.
**Custom Puzzles**
------------------
Continue exploring state space beyond the missions of the U.V.S. Nirmana by designing your own puzzles and observing as others solve them.
**Eternal Solitaire**
---------------------
A solitaire variant inspired by the traditional game Oware is included. Strategic play rewards insight into the future and an understanding of cause and effect.
**Histograms and Leaderboards**
-------------------------------
Optimal solutions are their own reward, however, those interested in comparing their work to others can do so with these features.

Feature extractions:
- Community Price:
  - Community fair range: $4.99 - $9.99
  - Reasoning: The reviews consistently describe a polished but very short logic-puzzle game that can justify a few hours of play, while experienced players criticize the low level count and poor value at full price. Several comments recommend waiting for a sale or say it is not worth full price, which pushes the community's fair base-game range down into the budget indie-puzzle tier rather than a premium price.
- Playtime Metrics:
  - Game completion: 10.0h
  - Story completion: 6.0h
  - Session length: 0.3h
  - Endgame: N/A
  - Reasoning: Multiple completion reports cluster around 4-7 hours for a normal finish, with 6 hours cited directly, so storyCompletion is 6. A thorough all-puzzle/optimization report and another total-playtime report cite 10 hours, supporting gameCompletion at 10. One reviewer describes daily 15-20 minute sessions, which translates to about 0.33 hours per session, so sessionLength is set to 0.33. No numeric duration is given for post-story bonus missions, custom levels, or leaderboard optimization, so endgame is null.
- Time-to-fun:
  - Summary: Most reports describe the game as rewarding and addictive from the start, with the optimization loop and steady introduction of new ideas making puzzles engaging early.
